Great job! I'm considering converting all my mp3 files to Vorbis format. Only examples/encoder_example is a bit too simplistic (of course, being an example), and the cmdline tools aren't ready. I encode my mp3 files at 96 kbit/s, because that's enough for me. Will Vorbis do well at this rate? Any quick hacks I can make to examples/encoder_example.c? Perhaps Vorbis is of interest to the GNU project. Anyone been in contact with them? --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

This is a minor, scheduled change, but it will break any bitstreams you encode now.> Perhaps Vorbis is of interest to the GNU project. Anyone been in > contact with them?RMS knows about us.

Well done Vorbis - expect increased attention. You made it to the front page of www.slashdot.org yesterday.

Especially if you're doing low bitrates. Taking a song that has already been somewhat mangled by mp3 and remangling it w/ ogg would be.. bad. I really think there aught to be a standard header flag in all of these formats stating wheither the file was encoded from original, clean, uncompressed input. __________________________________________________________________ PGP fingerprint = 03 5B 9B A0 16 33 91 2F A5 77 BC EE 43 71 98 D4 darxus@op.net / http://www.op.net/~darxus There is no fine line between genius and insanity. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

It also has a "copyright" bit, I'm sure we all make sure that's set when we encode mp3s. :) Tomas --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

And that's what I expected. But at a quick "glance" it didn't sound worse, either. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

Look into the ID3 v2 standard ( www.id3v2.org ), it a bit of overkill, but a standard, already supported by music player software.> Montydavid balazic P.S.: Hope the vorbis list allow posts from non-subscribers. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.
